    摘要:

    根据InP二极管的物理结构, 采用三维高频电磁仿真软件对其精确建模仿真, 获得二极管的物理模型和匹配电路的精确参数, 而后将此模型利用谐波平衡进行仿真设计.最后, 在此基础上采用InP肖特基二极管, 设计制作并测试了国内首款270GHz的零偏置检波器.检波器的最大电压响应度为1600V/W, 在260~280GHz范围内, 电压响应的典型值为1400V/W, 其对应的等效噪声功率典型值为18pW/Hz.实验结果与仿真结果比较吻合, 其结果表明, 设计方法较为精确, 具有设计简单、优化方便等优点.

    Abstract:

    According to the structure of the InP diode, 3-D high frequency simulate software was adopted to create accurate physical model and matching circuits of the diode. Harmonic balance simulation was used to simulate the whole circuits. Based on this type of InP Schottky diode, a 270GHz zero bias detector was designed and measured for the first time in China. The measured responsivity is near 1600 V/W at 260 GHz, as well as 1400 V/W over 260~280GHz typically, which corresponds to typical noise equivalent power level(NEP)of 18 pW/ Hz1/2. The measured and simulated results are highly similar, indicating that this solution has the advantages of accurate, simplified and easily optimized.
